Question

What is $E=m{c}^2$ ?

Answer 1

1. Physicist Albert Einstein introduced us to a famous energy equation that is $E=m{c}^2$.
   where, $E$ represents energy, $m$ represents mass and $c$ is the speed of light in air or vacuum.
2. According to the special theory of Relativity, we get infinite quantity of energy from body that has infinite mass.
3. The equation says that energy and mass are interchangeable, they are different forms of the same thing.
4. The energy is equal to the mass of the body times the square of the speed of the light.
5. In other words we can say that if a mass is moving with the square of the speed of the light then the mass will convert into energy.
